[Prior Art] With the rapid development of Internet and radio communication technologies, information technology has gradually become popular among individuals, so various portable information products such as notebook computers, mobile phones, digital cameras, and personal digital assistants are all In recent years, due to the thinness, light weight, low power consumption and no radiation pollution of LiqUid Crystal Display (LCD), the application of products in the low-yield Shibuya display of the early months has gradually The expansion of sophisticated surveillance or portable information products has become the mainstream of displays, gradually replacing the traditional cathode ray tube (CRT) display. In the case of a bovine case, the general liquid crystal display panel structure includes a thin-film transistor substrate 'TFT substrate, a color filter substrate (CF substrate), and is disposed between the two bases f. The liquid crystal layer. Please refer to the first figure. The first picture shows the architecture of the display panel. The display panel 1A includes a display area 14 on which a plurality of parallel data lines D1 to Dm and a plurality of scan lines sl1 to Sn parallel to each other are disposed. A pixel drive circuit 16 composed of electronic components such as a thin film transistor and a capacitor is provided at the intersection of each of the data lines D1 to Dm and each of the scan lines s^sn, and can receive = 4 m 201205520 = two, $ Dm The transmitted image data signal and the scan line s丨~Sn convey: switch/address signal 'to control the operation of the corresponding element. A conventional display panel is usually provided with a plurality of driving redundancy (DHvw IC) 20, for example, a driving ic of the liquid crystal display panel as an output 5 to a pixel to control the degree of twist of the liquid crystal molecules. The data line can be transferred to a Panted wiring board (pwB) (not shown) by means of a drive. According to different processes, the driver IC 2G can be divided into tape carrier package (Tape Carrier Package ' Tcp ), die soft mode bonding (ah (10) im' COF) or flip-chip glass (eight) called (10) (1) coffee, c〇g In the bean, the tape-and-reel wafer carrier package and the die-die bond are mainly used except for the (10) data lines D1 to Dm or the scan (four), and the other peripheral lines 22 and at least one repair line (four) 24) is used as an alternative circuit for the disconnection of the data lines D1 to Dm. In order to avoid the signal line or the scanning line breaking phenomenon to block the signal transmission, the general section is usually in the peripheral area of the display panel when the display panel is made. Set the xin f to ^ return line as the # generation line of the data line or the scan line. When the data line or the scan line is broken, the external transmission of the image data signal or „/address signal can still be repaired. Line transfer. 4 does not panel, to control the operation of the element, to avoid display panel display failure caused by data lines or scan lines. Under normal conditions, there is no electrical connection between the repair line and the bead line or scan line. Refer to the second figure.
